The compound X is

Options

A. `"LiAlH"_(4)//"ether"`
B. `H_(2)//Pd-BaSO_(4)`
C. `SnCl_(2)//HCl//H_(2)O,"Boil`
D. `NaBH_(4)//"ether"//H_(3)O^(+)`.

Answer

C

Explanation

`CH_(3)CH_(2)C-=Noverset(HCl)rarr[CH_(3)CH_(2)C-=NH]^(+)Cl^(-)`
`overset(SnCl_(2)//HCl)rarr[CH_(3)CH_(2)CH=NH_(2)]_(2)^(+)SnCl_(6)^(2-)`
`overset(H_(2)"O"//"Boil")rarrCH_(3)CH_(2)CHO`
